【摘要】 特殊安全多方计算已经成为安全多方计算领域中一个新的研究热点。研究了保密计算几何中的点包含问题,基于保密点积协议和百万富翁协议提出了一个半诚实模型下保护私有信息的点包含协议,并对协议的性能进行了分析。该协议在军事,工程研究和商业等领域有着重要的应用前景。更多还原

【Abstract】 Specific secure multi-party computation has been a new research focus in secure multi-party computation field. This paper focuses the point inclusion problem of private -preserving computational geometry. A new private-preserving point inclusion protocol in the semi-honest model is presented based on private-preserving dot product protocol and Millionaires ’protocol along with analysis of protocol’ capability. The protocol has potential applications in military, engineering research and commerce fields.更多还原
